JERGUSON;of Hull, in the county of De eef Florida; have invented a new andImprovedDrier, of which the following isafull, clear, and exactdescription.

The purpose of thisinvention'is to provide a rotary drum-drier of thatclass in which the material toibfefdriedis caused to'inovelongitudinally through the .revolving drum and in f which'a drierof'igiv'enl dimensionswill provide' a Agreater heatradiating r surfacethanl driers previously produced, thus increasing.

the eitlciency of the'drier, which eflieiencyof course depends upon theheatfradi-ating` sur-` 'fface thereof.

yThs specification isthe disclosure of one form of our invention,A Whilethe claims de- 2'0 une the actual scope thereof.

l Reference is to be had to theacoompanying drawings, forming a part,ofthis specification in which similar characters of Yreference indicatecorresponding parts in both the views. Figure l is a'lon'gitudinalvsection of the is an end view with parts broken away! j r v Y In driersofthe type towhich our inv-ention'relates the material to be dried inpassing'through the 'drum bears on the lower portonthereof andvislittleacted on by the npper portions' of.. the drum. Consequently a minimumdegree ofeffectivenessis attained.

Our invention consists in providing the drierx with 'a number oflongitudinal partitions, forminglas many contracted longitudi-l nalpassages t roughthe drier, through which passages the material to bedried is passed',

thus providinga large amount of radiating surface, and consequentlyincreasing' the efliciency of the apparatus. v

The cylinder'or body portion a of the drier is provided with thepartitions 7J, which in the Apresent instance are four in number and arearranged radially with respect tothe drum, bei ngsecu-red to the sidesofthe drum by angie-.irons c and to each other by angle-irons d, thusforming four .separate passages@ in the drum f The materialbeing passedthrough these passages is subjected to alarger radiating-surface, andconsequently more effectiveiy treated. y

.The feed'end f of the drier is provided with anumber of diagonalangle-iron ianges 9,.

which serve,r as the drum revolves, tofeed the Ymaterial toward thepartitions h. .1 -This mate- .rial is thrown into the end f and taken upby drum revolves and led The partitions l) are which the angle-irons asthe into. the passages e; provided with angle-iron`v ianges fr,

f serve to advance the stoel: along the drum.

These flanges h are useful only when the drum is 4mounted horizontally.When the drumis disposed at an incline, the ilanges h will notbenecessary.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. A drier-drum provided with a solidcontinuous diaphragm or parti-tion extending longitudinally through thevsaine to form the drum into a plurality of independent passages, saidpassa-ges extending from the oenterzof the drum to the sides thereofandl through which the material to be dried is passed, therebyincreasing the effective heating or radiating surface of the drum, and imeans-located at .the feed end of the drum for feeding the material tothe said passages substantially as described.

2. A drier-drum having a solidpartition iitted therein to form the drumintoa plurality of passages through which the stock maybe passed, andspirallydisposed flanges d mounted at the feed end of the drum toadvanoethe stock to the passages in the drum. A drier-drum, having asolid comin nous partition extending longitudinally*through the same toform the dr'u'rn into a plurality of independentpassages, through whichthe inat'erial to be dried may be passed, flanges attached to saidpartition to advance the stoel-1 along the passages, 'and flangesarranged spirally at the feed end of the drum tondv'ance thestock tosaid passages in the drum, sull stantialiy as described.

4. A'drier-drum having solid partitions arranged radizrliy with. respectto the drinn, :tn-

.gie-irons securing the partitions to the sides i of the dr'uunendangie-irons securing the partitions to each other at the center of thedrum, the feed end of the drum being provided with a series ofangle-irons arranged spil-ally on the inner surface of the feed vend. ofthe sirmmand serving, es the drum revolves, to feed the material int-othe passages, the said partitions being provided with angie-iron l`flanges to move the stock :dong

stantiaily as described.
